New data on RaC gamma intensities were developed with an improved high-resolving-power spectrometer. A specimen of RaBr/sub 2/ was used as the source; the background was 0.04 coincidences per minute at h nu = 1350 kev and less than 0.01 coincidences per minute at h nu = 1500 kev. The spectrum exhibits a 2017 kev line in addition to the previously identified 2117, 2204, 2292, and 2445 kev lines. An excess of recoil electrons with relative intensity approximately 1% from the 2204 kev line was found in the region h nu = 2270 kev. in the region 1700 to 2000 kev, the 1728 kev line separates from the 1764 kev line enabling a more precise evaluation of its intensity. The 1541 kev line was separated from the 1509 kev line. The 1583 kev line is twice as wide as the standard; explained by a new line at 1597 plus or minus 4 kev. The relative intensities of the lines are tabulated. An attempt to find the 2513 kev line indicated that should such line exist its half life is less thsn 5 x 10/sup -// sup 5/ quanta per decay.
