The spins and parities of the ground state and the first excited one are well known [6,15].

“…The levels in 74Ge populated by radioactive decay of 74As have been extensively studied by several authors [1][2][3][4][5][6]. Data on these levels have also been taken in (n, 7) [7], (p, p') [8], (t, p) [9] and Coulomb excitation studies [10][11][12].…”

“…Instead, there are discrepancies in the spin assignment for the 1,270keV level and in the branching ratio of the gamma transition which deexcites it. Studying the V4As decay, Kubok et al [4] established the spin as 0 + or 4 + whereas Van Hise and Paperiello [6] Fig. 1.…”

Abstract. Directional-correlation measurements of several cascades in the 74As decay have been made with a NaI-Ge(Li) detectors system. In the 74Ge the following cascades were measured: 608-596 keV, 994-1,204keV, 994-(608)-596 keV and 887-596 keV. The corresponding results give a unique spin assignment of 2 for the 2,198 keV level and determine the E2/M1 mixing ratios of ~(608)=3.4+0.4 and 6(994)=-(2.8+0.2). In the ~4Se it was measured the 635-635 keV cascade. The result obtained assigned the spin of the 1,270keV level as 2 and fixed the E2/M1 mixing ratio of 6(635)=-(2.6+0.2). Also a 3,-intensity study has been made to determine the branching ratios of the transitions that deexcite the 1,270keV level in 74Se. From these data a I(635)/I(1,270)= 12.5_+5.0 is obtained.

The K-Fluorescence Yield cox of Germanium has been measured using the coincidence method and investigating the decay of V4As. The branching ratios of this decay had to be measured and all relevant determining values, as detection efficiencies, absorption coefficients etc. The experimental results are P~coK = 0.494_+ 0.012 and OK = 0.561 +0.015 using PK=0.881 +0.003. For the branching ratios of the decay of 74As we obtained
