High-spin spectroscopy of I-122Singh, Purnima; Nag, Somnath; Selvakumar, K.; Singh, A. K.; Ragnarsson, Ingemar; Bisoi, Abhijit; Goswami, A.; Bhattacharya, S.; Kumar, S.; Singh, K.; Sethi, J.; Saha, Sudipta; Trivedi, T.; Jadhav, S. V.; Donthi, R.; Naidu, B. S.; Palit, R.High-spin states in 122 I have been investigated using the 116 Cd( 11 B,5n) 122 I reaction at a beam energy of 65 MeV and γ -ray coincidence events were recorded with the INGA spectrometer. The level scheme of 122 I has been extended up to spin I = 30. Experimental features, such as band-crossing frequencies, aligned angular momenta, signature splitting, and B(M1)/B(E2) ratios have been used for configuration assignments to low-energy band structures. Maximally aligned states involving all eight particles outside the 114 Sn core and states with one particle antialigned have been identified. Cranked Nilsson-Strutinsky calculations have been used to interpret high-spin structures.

Although stock trays often provide mechanical retention for elastomeric impression materials, manufacturers typically recommend the use of an adhesive, whether a stock or custom tray is used. The mention of the bond strength on the adhesive packaging is not available, therefore the clinician has no idea whatsoever of the ideal adhesive. The aim of this study was to evaluate the bond strength of three vinyl polysiloxane (VPS) materials, one with a poly(methyl methacrylate) autopolymerizing (PMMA) specimen and another with a light-polymerizing tray material (VLC), using the adhesive recommended by the manufacturer of the impression material, and two universal adhesives. A total of ninety specimens (15 × 15 × 20 mm) were used, 45 specimens were made in PMMA and rest 45 was made in VLC. Five paint-on adhesives (Coltene, Caulk, 3M, universal Zhermack and universal GC) were applied. Three impression materials, Affinis, Reprosil, and 3M, were mixed and injected into a perforated poly vinyl chloride cylinder. Tray specimens were positioned against the open cylinder end in contact with the VPS material. Tensile strength tests were conducted until adhesive separation failure. Mean values and standard errors of the adhesive strength were recorded in MPa for each material combination. GC paint-on universal adhesive provided significantly higher adhesive strength values.
