Scientific paper

Photoelectric scans of the spectrum of SN 1972e are presented. The observations were obtained at the McDonald Observatory between 15 and 50 days after maximum light with a spectral resolution ranging from 4 to 20 A. Line identifications (Ca II, Fe II, Si II, and possibly He I) are discussed briefly. It is suggested that the emission feature identified by Kirshner and Oke (1975) as H alpha may have been produced by Fe II.
