We present the results of the H i line and the radio continuum observations of five nearby E+A galaxies. These galaxies are selected from a unique sample of 21 E+A's identified by Zabludoff et al. (1996) in their spectroscopic search for E+A galaxies using the Las Campanas Redshift Survey, where over 11,000 nearby galaxies were examined. We have detected H i emission in one E+A galaxy, EA 1, with a total flux of 0.30 +/- 0.02 Jy km s(-1) and a H i mass of 4.3 +/- 0.3 x 10(9) Msun. The H i morphology and kinematics of EA 1 suggest a galaxy-galaxy merger. A lower limit to the time since the merger happened is ~ 8 x 10(8) yrs, which approximately agrees with the general interpretation that starbursts ceased within the last ~ Gyr in E+A's. If the other E+A's had the H i properties of EA 1, the closest of the sample galaxies, we would have detected them. Therefore, we conclude that E+A galaxies have a wide range of H i masses. None of the galaxies were detected in radio continuum emissions. The upper limits on the radio power are ~ 10(21) h(-2) W Hz(-1) , which exclude the possibility that these galaxies have dust-obscured, on-going starbursts.
