get list of objects and keep the object symbol as names

When making a list of objects, is there a way of keeping the object symbols to use them as names in the list?

The below uses get and re-assigns names afterwards, and I wondered if there is another approach. 

a_1 <- 1
a_2 <- 2
a_3 <- 3

ls_a <-  lapply(ls(pattern = "a_"), get)
names(ls_a) <- ls(pattern = "a_")

ls_a

#> $a_1
#> [1] 1
#> 
#> $a_2
#> [1] 2
#> 
#> $a_3
#> [1] 3

mget has this as a default behavior. 

mget(ls(pattern = "a_"))

#$a_1
#[1] 1

#$a_2
#[1] 2

#$a_3
#[1] 3
