The transitional nuclei 42 100 Mo, 44 104 Ru, and 46 108 Pd have been studied as products of binary reactions formed by a 36 86 Kr beam impinging on a 46 110 Pd target. The yrast states are observed above the region of the first backbend. In each case this backbend is associated with the breaking of the first neutron (h 11/2 ) 2 pair. The results are consistent with the predictions of cranked shell model calculations and the systematics of neighboring nuclei. ͓S0556-2813͑97͒01904-3͔ PACS number͑s͒: 21.10.Re, 23.20.Lv, 25.70.Ϫz, 27.60.ϩj 42 100 Mo, 44 104 Ru and 46 108 Pd are 0.72, 0.73, and 0.74 respectively.Gamma rays from decays in both the targetlike and projectilelike fragments were measured using an array of 12

This paper presents innovative algorithms for optimum filtering, rise-time discrimination and proper correction of solid-state detector pulses based on digital pulse processing (DPP) techniques and on a Linear Sliding Method. These techniques allow a significant improvement on the spectral resolution by taking into account both the electronic noise and the pulse rise time fluctuations mainly due to the incomplete charge collection in the CZT crystal. In order to develop these algorithms pre-amplified pulses coming from a planar XR100-T detector (Amptek) were digitized by a 12-bit PCI acquisition card (125 MHz) hosted by a PC platform. The presented results show that, due to the possibility of fine adjustments on the discrimination and correction parameters during the processing stage, this flexible DPP implementation leads to significantly better results than the analog hardware discrimination solution. Comparative analysis of Am-241 spectra show a significant reduction of the low-energy ''tail'' on the 59.5 keV photo-peak. r
