• Short-lived molybdenum isotopes produced by the <SUP>236</SUP>U(<I>n, f</I>) reaction were isolated by rapid paper electrophoretic technique. Gamma-ray spectra of the isolated molybdenum fraction were measured with high resolution Ge(Li) detector. The half-lives of <SUP>103</SUP>Mo (70±1sec), <SUP>104</SUP>Mo(66±2sec) and <SUP>105</SUP>Mo(30±3 and 40±5sec) were determined by analyzing the genetic relationships of the known photopeaks of their technetium daughters. Decay analysis of observed photopeaks free from interference resulted in the detection of many new short-lived photopeaks with half-lives of 1070 sec, and which were not relevant to technetium isotopes. These new photopeaks were ascribed to <SUP>103106</SUP>Mo based on examination of their decay behavior.
