“…Although more fragmented in 133 Xe, the structures of the negative-parity states above J π = 11/2 137 Ce, before emerging again in 139 Nd. However, the 2389-keV state in 135 Ba, which was assigned with spin J = (21/2) by both Che et al [72] and Cluff [70], later revised to spin J = (23/2) by Kumar et al [38], could be an isomer candidate. Higher-lying (first excited) 23/2 + states are known in 135 Ba and 137 Ce which do not fit the N = 79 systematics.…”

The transitional nuclei 132 Xe and 133 Xe are investigated after multinucleon-transfer (MNT) and fusionevaporation reactions. Both nuclei are populated (i) in 136 Xe + 208 Pb MNT reactions employing the highresolution Advanced GAmma Tracking Array (AGATA) coupled to the magnetic spectrometer PRISMA, (ii) in the 136 Xe + 198 Pt MNT reaction employing the GAMMASPHERE spectrometer in combination with the gas-detector array CHICO, and (iii) as an evaporation residue after a 130 Te(α,xn) 134−xn Xe fusion-evaporation reaction employing the HORUS γ -ray array at the University of Cologne. The high-spin level schemes are considerably extended above the J π = (7 − ) and (10 + ) isomers in 132 Xe and above the 11/2 − isomer in PHYSICAL REVIEW C 96, 024321 (2017) isotones. Shell-model calculations employing the SN100PN and PQM130 effective interactions reproduce the experimental findings and provide guidance to the interpretation of the observed high-spin features.

Analysis of pseudoscalar and scalar D mesons and charmonium decay width in hot magnetized asymmetric nuclear matter

In this article, we calculate the mass shift and decay constant of isospin averaged pseudoscalar (D + ,D 0 ) and scalar (D + 0 ,D 0 0 ) mesons by the magnetic field induced quark and gluon condensates at finite density and temperature of asymmetric nuclear matter. We have calculated the in-medium chiral condensates from the chiral SU(3) mean field model and subsequently used these condensates in QCD Sum Rules (QCDSR) to calculate the effective mass and decay constant of D mesons.Consideration of external magnetic field effects in hot and dense nuclear matter lead to appreciable modification in the masses and decay constants of D mesons. Furthermore, we also studied the effective decay width of higher charmonium states (ψ(3686), ψ(3770), χ c 0 (3414), χ c 2 (3556)) as a by-product by using 3 P 0 model which can have an important impact on the yield of J/ψ mesons.The results of present work will be helpful to understand the experimental observables of the heavy ion colliders which aim to produce matter at finite density and moderate temperature.

“…Within the chiral effective model [75][76][77], the in-medium charmonium masses are obtained from the medium changes of a scalar dilaton field, which mimicks the gluon condensates of QCD [27,78,79] and the mass modifications of the D andD mesons arise due to their interactions with the baryons and scalar mesons in the hadronic medium [27,[78][79][80][81]. The chiral effective model has been used extensively in the literature, for the study of finite nuclei [76], strange hadronic matter [77], light vector mesons [82], strange pseudoscalar mesons, e.g.…”

We study the partial decay widths of the charmonium states (J/ψ, ψ(3686), ψ(3770), χ c0 , χ c2 ) to DD (D + D − or D 0D0 ) in isospin asymmetric nuclear matter, in the presence of strong magnetic fields.The in-medium partial decay widths of charmonium states to DD are calculated within a light quarkantiquark pair creation model, namely the 3 P 0 model, using the in-medium masses of the charmonia as well as D andD mesons in the magnetized nuclear matter, obtained within a chiral effective model.The presence of a magnetic field leads to Landau quantization of the energy levels of the proton in the nuclear medium. The effects of magnetic field and isospin asymmetry on the charmonium decay widths to DD are found to be quite prominent. The effects of the anomalous magnetic moments have also been taken into consideration for obtaining the in-medium masses of these heavy flavour mesons, used to calculate the partial decay widths of the charmonium states. The medium modifications of the charmonium decay widths can have observable consequences on the production of the charmed mesons in high energy asymmetric heavy ion collision experiments.
