“…In the range of 500-1000 keV the FWHM energy resolution and the add-back photopeak efficiency of the DALI2 + array were 13.5% (500 keV)-10.8% (1000 keV) and 45% (500 keV)-30% (1000 keV), respectively. Further details of the DALI2 + setup, the Doppler correction, the add-back procedure as well as the MINOS device, and the track reconstruction can be found in the previous papers on this experiment [20,22,[24][25][26][27][28][29][30][31] and elsewhere [35][36][37].…”

“…The secondary radioactive ion beam consisted of many nuclei with a range of the atomic number Z = 17-24 and that of the mass-to-charge ratio A/Q = 2.5-3.0, which provided a rich ground for new results published earlier. The details of the setup were discussed in the corresponding papers [20,22,[24][25][26][27][28][29][30][31], therefore only some relevant parts were reviewed here, specific for the nuclei and reactions in question.…”

“…Therefore, this region came also into the focus of experiments including the cobalt [9,10], iron [11][12][13], manganese [14,15], chromium [16][17][18], and titanium [19][20][21] isotopes. For the N = 40 isotones, by removing protons from 68 Ni, the results showed an increase of collectivity up to 64 Cr (reaching a quadrupole deformation parameter β 2 of around 0.3 [13]), and a decrease toward the drip line in 63 V (β 2 = 0.24) [22]. The location of the first 2 + state in 62 Ti suggested a further decrease of the deformation [20].…”

“…All these theoretical approaches were exactly the same as those we used in our previous publication [22], in which they were thoroughly discussed, therefore only some fundamental parts are repeated now. The shell-model calculation was performed with the code ANTOINE [59,60], and the Hamiltonian based on the LNPS [8] interaction.…”

Effective polarization in proton-induced $α$ knockout reactions

“…In recent years, a series of (p, pN ) measurements has provided us with new findings on the s.p. structure and the magicity of unstable nuclei [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Very recently, the first direct observation of α particles knocked out from Sn isotopes was reported [20].…”
